Comedy Preview: Edinburgh Previews 19-25 June

We've told you before how much we like previews and now we have a chance to do so again: as ever, comedians all over London are sweating heavily, desperately trying to finalise, hone and polish their shows before heading oop North to Edinburgh. Which means we get to see cheap comedy and witness some birthing pains (but with much less mess, though perhaps just as much screaming).

Sketch marvels Idiots of Ants have three shows this week that promise to reveal why Tom and Jerry hate each other, and their new computer game "Urban Sword Fighter 3". Catch them on Saturday at the Etc Theatre or Wednesday and Thursday at the Hen and Chickens. Etcetera Theatre, 265 Camden High Street, Saturday 20 June 9.30pm, £6.50 / Hen and Chickens, 109 St Pauls Road Islington, 24-25 June 7.30pm, £6.

Richard Herring offers a glimpse of his Hitler Moustache at pretty much every venue in town, but we're going to plump for the Wimbledon Theatre on Monday - with Jimmy McGhie regaling audiences with his tale of a disastrous Highlands party, and The Albany on Thursday with Mat Ricardo, "gentleman juggler". New Wimbledon Theatre, The Broadway, Monday 22 June 7.30pm, £10 / The Albany, Douglas Way, Deptford, Thursday 25 June 8pm, £10 / £8 / £6.

Also appearing in Wimbledon are Perrier winning Laura Solon with some new character-based comedy, and Dan Atkinson, dying a Death by a Thousand Pricks - which has a lot to live up to after he sold out last year. New Wimbledon Theatre, The Broadway, Tuesday 23 June 7.30pm, £10.

Paul Sinha would like to tell you about 39 Years of Solitude at the Chapel Bar on Tuesday, where you can also catch shaggy haired Perrier nominee and Hyperdrive actor Dan Antopolski. He promises to be Silent But Deadly. The Chapel Bar, 29a Penton Street Islington, Tuesday 23 June 7.30pm, £7 / £5.
